A megapixel is one million pixels. It is commonly used to describe the resolution of digital cameras. For example, a 7.2 megapixel camera is capable of capturing roughly 7,200,000 pixels. The higher the megapixel number, the more detail the camera can capture. Therefore, the megapixel count is a significant specification to look for when buying a digital camera.

Overview

The Canon EOS 5D Mark III - (Body Only) is certainly the best digital camera among its peers without any argument. Offering a truly unique experience with its high-end features and loaded components, the EOS 5D Mark III sports a highly durable magnesium-alloy body that is not just tough but also is safe against natural elements of dust and moisture. Contributing to a wealth of speed throughout the camera system, it is loaded with a 22.3MP full-frame CMOS sensor and DIGIC 5+ Image Processor. The 3.2" clear view II LCD monitor lets you enjoy the images and videos in crystal clear quality. With its high-end features and revolutionary functionality, this camera is certainly a treasure for the professional as well as beginners in photography.

Optics and Focus

With enhanced optical elements from Canon, this camera is enabled with Canon EF lens mount. Featuring a newly designed 61-point autofocus interface with 41 cross-type AF points and 5 dual diagonal AF points, it helps in achieving the best results in all conditions. With dedicated AF menu tab, the complete access and operability has never been so much easier than this. Get the best results from its 14-bit signal processing. While it provides an increased ISO range of 50 to 102400 in the expanded modes, the camera helps in achieving 100 to 25600 in standard modes. Not just that, it lets you customize the ISO range according to your preference, allowing you to enhance your photo shoots in varied lighting situations.

Sensor and Screen

Incorporated with a 22.3MP full-frame CMOS sensor, the 5D Mark III is a brilliant performer and delivers rich images at a maximum resolution of 5760 x 3840 pixels. It also greatly reduces the image noise and helps in achieving high ISO performance. With a 1,040,000-dot resolution, the 3.2" Clear View II LCD screen surprises with sharp and clear viewing of images and videos. Further enriching the visibility is the anti-reflection coating that clearly answers the highly detailed richness of the image. You can also set the dual axis electronic level for a full display of 360° of roll and +/- 10° of pitch in 1° increments. Moreover, the placement of grid lines helps in precise control and alignment during composition.

Image and Video

Boasting an efficient DIGIC 5+ Image Processor, the 5D Mark III outperforms its peers with its superfast speed and improved performance. Delivering the best results, this camera is incorporated with new algorithms that enable achieving better noise reduction. Aiding in the delivering 6 full-resolution frames-per-second, the processor vouches for the increased processing speed. With new 61-point high density reticular autofocus and 41 cross-type AF points as well as 5 dual diagonal AF points, it promises great sharpness. You can also record full HD video 1080/30p and 720/60p utilizing the HDR and Multiple Exposure modes.

Other Features

On the connectivity features, the 5D Mark III is so much astounding that there is literally no comparing peer to compete its capabilities. Enabled with WFT-E7A Wireless File Transmitter, it supports 802.11 a/b/g/n. The built-in Gigabit Ethernet connection helps in faster data transfers through LAN and Bluetooth. Utilizing the GP-E2 GPS Receiver, the camera orients the location to a compass reading when shooting, thus enabling precise GPS time sync function.

Allows a delay between pressing the shutter release button and the actual firing of the shutter. Commonly used to give photographers time to put themselves in the shot and to take photos without having to physically have their hands on the camera during exposure.

To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended.

The ISO speed setting dictates sensitivity to light. The higher the ISO speed, the more sensitive the film or digital sensor is to light. Higher ISOs have the effect of noise in an image. The actual ISO at which the noise occurs varies from camera to camera. Low ISOs are generally used for brighter lighting conditions and high ISOs are often used for low light or action shots.

The various modes in which the camera will measure light. Most DSLRs and some advanced point and shoots have the ability to meter an entire scene (matrix/evaluative) or a specific point (centerweighted/spot)

A flash that is embedded or part of the camera. Built-in flashes are found in both DSLR and Point & Shoot cameras. Although practical because of their small size and ease of use, built-in flashes are often ineffective and/or unflattering as a main source of light.

Refers to the option for the user to override the internal light meter in the camera to either OVER or UNDER expose based on middle/18% gray. This is especially useful when photographing either extremely white/bright scenes or when in very dark/dimly lit scenarios.

The types of files that a particular camera produces. All cameras output JPEG images, but some of the more sophisticated models will shoot in RAW mode. RAW Image Formats will vary based on manufacturer.

Refers to the actual physical size of the imaging sensor in the camera. A sensor that has the same dimensions as a 35mm frame of film is considered to be "full" frame. Other smaller sensor sizes are described in terms relative to a "full" sized sensor. (e.g. an APS-C 1.5x crop sensor)
